Plants
This is the part of the plants where photosynthesis happen.
Leaves
How do we call animals that have backbone?
Vertebrates
Give 1 effect of force.
-Can make stationary object move
-Can make a moving object move faster or slower
-Can make a moving object stop
-Can make a moving object change directions
-Can change the shape of an object
Arrange the letters in correct order..
smas
mass
_________ is the amount of gravity acting on an object.
Weight
What is the function of the fruit?
- it protects the seeds.
Say something about invertebrates.
These are group of animals that don't have backbones.
Who discovered gravity?
Sir Isaac Newton
Will a person's mass change if he moves from one place to another? Yes or No.
No
What is the unit of weight?
Newton
Tell us anything you know about the stomata.
It helps in removing water from the leaves.
It takes carbon dioxide and gives out oxygen during the process of photosynthesis
It helps in regulating water movement through transpiration. Stomata facilitates gaseous exchange
What is the difference of warm-blooded and cold-blooded animals.
Warm-blooded animals can maintain their body temperature even if it's hot or cold.
Cold-blooded animals depend on the temperature on the environment.
This a force that pulls objects towards the earth.
Gravity
Wasawat's mass is 40 Kilograms, if he goes to the moon, will he have the same mass?
Yes
What instrument is used to measure weight?
spring scale balance
What are needed in order for photosynthesis to take place?
1. Sunlight
2. Water
3. Carbon dioxide
4. Chlorophyll
Tell us something about amphibians.
•Are cold-blooded.
•Lay eggs.
•Have a smooth, moist skin. (ผิวชุ่มชื้น)
Adult can live on land as well as in the water
Sittipanh is 39 kilograms and Pawothai is 30 kilograms. Who has a greater gravity?
Sittipanh
What are the units of mass?
Kilograms (Kg) and Grams (g)
Patrapee's weight will change if he goes to the moon. Why?
Because weight depends on the pull of gravity and the moon has a lesser gravity than the earth.
What are the functions of xylem and phloem?
Xylem - water and mineral transport from roots to parts of the plant.
- Moves up the plant's stem
Phloem – transport food and nutrients from leaves to the parts of plant.
- Moves up or down the plant's stem
What are the 5 groups of vertebrates? Give 1 sentence for each.
1.Mammals (สัตว์เลี้ยงลูกด้วยนม) - •Feed their babies with their own milk. They have mammary glands. (เต้านม)
2.Birds - Have feathers. (ขน)
3.Reptiles (สัตว์เลื้อยคลาน) - Have a dry skin
(ผิวแห้ง) covered with scales
4.Amphibians (สัตว์ครึ่งบกครึ่งน้ำ) - Adult can live on land as well as in the water
5.Fish - Breathe through gills.
Tell us anything you know about gravity.
-It’s a force that pulls objects towards the earth.
-Anything which has mass also has a gravitational pull.
-The more massive an object is, the stronger its gravitational pull is.
(More mass=more gravity)
Say something that you know about mass.
The mass of an object is the amount of matter that makes up that object.
It does not change wherever it’s placed.
The units are grams (g) and Kilograms (Kg)
Beam Balance - an instrument used to measure mass.
Tell us anything you know about weight.
Weight is a force acting on an object.
It changes depending on the strength of gravity.
It's unit is in Newton.
Can be measured by a spring scale balance.
